There can be situations when your car’s fuel pump might incur some complications. Therefore, it is better if we realize these situations beforehand and take care of them. The below article walks you through the top ten most common symptoms of a bad fuel pump that needs replacement as soon as possible. 

Top 10 Symptoms of a Bad Fuel Pump

There can be situations where you might have to deal with premature fuel pump complications. Therefore, every driver should make it a point to familiarize themselves with different symptoms indicating that they are dealing with a bad fuel pump.

1. Issues starting your vehicle

The first and most common symptom that you will face is difficulty starting your vehicle. Typically, difficulties in starting your vehicle have a lot to do with the battery and the starting system, but if all these parts are in good condition, then you have to check out the Fuel pump because it could be the culprit. 

2. Engine stalling

When the fuel pump is not working properly, you can easily deal with engine installation. So, before your mechanic goes ahead and considers replacing the fuel pump, make sure that he performs a full inspection of all potential culprits first.

3. Rough idling

When you idle, your vehicles shouldn’t be very rough, and if at all this happens, it could be a sign of internal problems that could vary from very simple to supercritical. 

4. Engine misfiring

Engine misfiring occurs when there is an issue with one of three important components: the air supply, the fuel supply, or spark timing. For example, if you happen to have a bad fuel pump, there is inconsistent fuel supply to the cylinders, and it’s not surprising to deal with the engine misfiring immediately after the fuel pump fails or is about to fail. 

5. Hesitation when accelerating

Have you ever come across a situation wherein you are trying to hit the gas pedal and realize that your vehicle hesitates before it starts to accelerate? That could be a case of a potential outcome of a bad fuel pump. 

6. Significant variation in engine speed

When the engine does not receive the right amount of fuel all the time, it will not provide you with the constant speed that you’re looking for thereby affecting the fuel pump.

7. Power reduction

Your engine will start to give up when there is an inconsistent supply of fuel and that is where you will notice a significant reduction in the overall power or probably a complete vehicle shut off. 

8. Reduced vehicle performance

Performance is also not limited to power because your vehicle must immediately behave and respond to your actions. 

9. Higher fuel consumption

In situations when the fuel pump is not working properly, it leads to fuel overconsumption.

10. Check engine light illuminating

Finally, all the symptoms above can easily trigger the check engine light. The check engine light is a critical symptom that indicates that your vehicle has some internal issues. 

The fuel pump is a core component of your vehicle, and without it, your engine won’t work, and hence your car won’t start. Therefore, every driver must understand when this part is incurring any problems and what are the common symptoms of a bad fuel pump.
